HARVE STER-BINDER.

SPECIFICATION formingpart of Letters Patent No. 251,906, dated January 3, 1882.

Application filed June 12, 1879.

To all whom it may concern Be it known that I, SYLVANUS D. LOGKE, of Hoosick Falls, in the county of Rensselner and State of New York, have invented a certain new and useful Improvementiu Harvester- Binders; and I do hereby declare the following to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming part of this specification, in which v Figure l is a top plan'view of a harvester having myimprovements applied thereto. Fig. 2 is an end elevation of the same. Fig. 3 is a rear elevation 'of a portion of the same. Fig. 4. is a detail view, showing the position of the binding-arm while ejecting a bound gavel. Figs. 5 and 6 are detached views of the cast ings and traveler-rods upon which the frame of the binding mechanism is supported and adjusted. Fig. 7 is atop plan view of the plate 0 detached. Figs. 8, 9, 10, and 11 are views showing the details of the twisting and cutting mechanism.

Similar letters of reference in the several figures denote the same parts.

The objectof this invention is to improve the construction and operation of automatic grain-bindin g machinery; and to this end the invention consists, first, in. an improved construction for the adjustment of the bindinghead and band-carrying arm to the length of the grain or the position of the grain on the binding-table; secondly,in an improved means for accomplishing the movement of the bandca-rrying arm; thirdly, in an improved separator and compressor; fourthly,in animproved spring device to assist the looping-hooks by guiding and bending the wire properly during theiroperation; and, lastly, in the several com binations of mechanism whereby the general objects of the machine are carried into'prac tice. r

In the drawings, A represents the harvester, which, in the form here shown, contains the usual cutter, or, the platform a, an endless apron-carrier, a an elevator, a draft-tongue a, draft-wheels a a", drivers seat a and binding table or plat-form B, these several parts, with their necessary and usual accessories, being of any approved form and construction.

Upon an ofl'set, a", of the harvester -framc per surface of the castings between the lugs,

as shown. The rods may be secured by pins,

keys, or other means, so as to be removable when desired. These two rods pass through downwardly-extending projections or legs 9 of an upright movable frame, G, which supports and adjusts the binding head and arm. Near theirends thecastin gs are provided with flanges f f behind which the legs of the frame G willbe securely held while the traveler-rods are introduced and securedin place. By means of a lever, H, the driver from his seat can slide the frame ,G back and forth upon the travelerrods, and thus adjust the position of the binding mechanism to the length or position of the grain on thebinding-table. The upper end of the frame G is stayed and guided by braces J J, secured to a sliding guided plate, J which devices are made the subject of a pending application for LettersPatent filed by me, and therefore need not be specifically described herein.

O is the main driving-wheel which actuates the holding and twisting mechanism and the band-carrying arm. It is continuously rotated in the direction of the arrow'by any suitable means-as, for example, by circumferential cogs meshing into a sliding feathered pinion or trundle, la, on a shaft, K, which in turn is driven by any suitable connection to the main power shaft or wheel of the harvester. The sliding pinion It automatically adjusts itself on its shaft to the position of the main wheel 0, as the latter may be fromtime to time adjusted by the movement of the lever H. The shaft D of wheel 0 passes horizontally through the lower arm of the casting G, and, projecting at the angle or corner thereof, is provided with a bevel-pinion, cl. The latter meshes into a similar pinion, d, on the lower end of a vertical shaft, D, which has its hearings in the upright part of the casting G. At the upper end of the vertical shaft 1) is another bevel-gear wheel, d having only a. mutilated-gear rim ICC and provided with suitable delay-surfaces,

which wheel d drives intermittingly a bevelgear, d, on the end of a horizontal shaft, D

as aforesaid, a peculiar movement is imparted to theband-carrying arm, which movement is fully represented in Fig. 3. When the bandcarrying arm arrives at the point represented at 2 in said figure the wheels 11 d run out of gear and the arm remains in that position till.

the cutting and twisting is effected, when said wheels again come into gear and the arm moves forward to the point marked 3, thereby ejecting the bound gavel from the machine. The arm then rises and moves back rapidly, its point following the course of the dotted line in the direction of the indicated arrow. At the lower end of the casting G is an arm, 9 projecting up by the side of the wheel 0, which arm supports a bracket, 0, having a flat top which extends over said wheel, and at the opposite side of the wheel is provided with a downwardly-e101] gated tubular bearin g, 9 containing a hollow vertical shaft, m, within which is arranged a longer vertical shaft, n.

Shaft m carries at its lower end a small-pinion, m, and delay-plate m and at its upper end a revolving hooked arm, a, while shaft n carries at its lower end a similar pinion, a, and a delay-plate, a and at its upper end an S-shaped looping and twisting hook, 8.

0n the side of wheel 0 there is arranged a segment-gear rim, 0, which actuates the pinion n, and some of whose teeth 0 are elongated, so as to mesh with the wheel m and give it one revolution. Grooves e o permit the rotation of the delay-plates when the gearrims are in.

engagement, as aforesaid, while the smooth face of the wheel 0 at other times, being in steel plate, 0, which presses upward with yielding force against the under side of the hook s. The shaft n passes through one end of the plates 7' 0, while screws to serve to secure their opposite ends upon a rib or projecting surface, 9 of the arm 9 The upper edge of the hook e revolves in close contact with the under side of the plate 1, for the purpose of acting in connection therewith to sever the wire; but beneath this hooke is a holder-plate, on which the end of the wire is clamped by said hook, as hereinafter described. The ends of the wireare snubbed over the plate 0 by the initial movement of the twister, and in its further revolution are clamped and held in their snubbed condition between its arms and the plate. Thelatter therefore must have considerable area, that the ends of the wire may be properly supported. One mode of coustructin g it is shown in Fig.7. As there represented it is recessed in its upper surface immediately around the shaft n, so as to form an. annular depression or bed,'v, around said sh aft. It is also cut away at a, and from the angle of the gain or notch thus cutout a groove, 0 leads into the depression or bed a. This plate 0 fills up the space under the twisting-hook s, and it acts withaJyielding force to admit the wire to enter between it and the book. The primary function of this plate, as above stated, is to hold the wire close up under the twistinghook, thereby bending it at an abrupt angle and causing it to be held without danger of slipping or drawing out of the hooks as the twister revolves. The function of the recess a and its surrounding rim or flangev is to guide the wire close to the shaft while twisting, thus preventing its ends from escaping from the twistinghook until properly twisted. The

groove a is to facilitate the passage of the wire into the recess a, and the lateral notch 71 is to guide the wire into the groove a The operation of these binding-devices will be more fully explained hereinafter.

Tis a separating and compressing arm, projecting downward from an arm,g of the casting G." It is secured to said arm by a'lateral arm or trunnion journaled therein, which per mits the lower end ofthe separator or compressor to be rocked or swung backward and forward. A stop, it, limits its backward swing and a spring, t, holds it normally back against the stop with a yielding force.

The binding-table is provided with the usual guides, B B, slot B and yoke B and it is secured to the casting G, so as to be adjusted therewith and always preserve thesame relation to the binding mechanism. The means for thus securing it are immaterial; but bolts or screws passing into or through the head of the arm 9 and another similar arm will answer the purpose as well.

To the upper surface of the binding-table, at the side of the slot, there are secured a flanged and notched metal plate,b b, and a flanged underlapping plate, b which two plates iorm a peculiar gateway for the passage of the bandcarrier, as well as a guide and holder for the band material. They also serve to deflect the grainand dirt away from the slot and protect the working parts underneath; but these flanged and notched plates and the gateway formed by them form subject-matter in Letters Patent No.238,939, granted to me March 15, 1881, and are not claimed herein.

The mode of operation of the above-described machine is as follows: The wire is first put through the eye of the needle or arm, and the end is temporarily held in the usual manner, as by the hand of the operator or by being fastened at any point on the arm near its articulation with the crank. The machine is then started up, causing the arm to sweep downward and forward and bring the wire into the hook-notch L The arm then stops by the unturn the twisting-hook about three-quarters of a revolution, causing one of its arms to catch hold of the wire and bend it over the top of plate 0. Then thelong gear-teeth a come in -contactwith the pinion m and revolve the arm e once around, whereby towardtheendof its revolution it seizes and clamps the wire between it and the top of the part g beneath,

and cutsofithe upper end ofthewire by forein g it against the sh arp-ed ged plate 1, the hook s meanwhile continuing to revolve. Then the pinion m passes 0d of the long teeth, while the.

pinion a, still engaged with the short teeth,

continues to revolve, carrying the hook 8 around several times, and at length becomes disengaged after a full number of revolutions,

leaving the hooks in their original position, with the end of the wire clamped and the machine ready for work. It will be observed that to accomplish these movements there areseveral short teeth of rim 0 arranged in advance of the long-tooth rim 0, whose first function is to reverse the hook s before the clamping-hook 6 begins to operate. There may be four, six, or anyothersuitable number ot'these advanced teeth that will properlyaccom plish this object, and will rotatethe twister far enough in advance of the cutter to loop the ends of the band underneath the former and prevent their being withdrawn by the expansion of the bundle, or otherwise, before the twisting is completed, as described. The number of long teeth should be equal-to the number of teeth on pinion m, so as to cause one revolution thereof. The whole number of teeth which act on the pinion a should be some integral multiple of the teeth n,'in order to give ita desired number of full revolutions, which number may be greater or less, as it may. be preferred to twist the band more or less. The machine, having been thus prepared, is put to its work, and the cut grain from the elevator is dropped upon the binding-table behind the separator T, which, in

7 connection with the wire held in the needle or band-carrying arm, keeps the grain from passing too tar forward. The arm I rises, passes back above the grain, and descends, carrying the wire around the gavel, and then sweeps outward,compactingand condensing the gavel against the compressing-arm T, which yields, swings forward, and rests on the front and upper side of the gavel as the arm I reaches the strand carried by the needle or arm I. As this strand is in turn seized by the hook sthe bandcarrying arm ceases for a time to move and awaits the completion of the twisting. Almost simultaneously the clamp arm 0 passes out from neath, and cuts it off above.

under the plate 1" and releases theend of the clamped strand, and then for an interval the hook twists the two strands while neither of them is clamped; but when the arm 6 comes around it engages with the strand held by the band-carrying arm, clamps it as before under- Both strands are now out off and free from the clamp, but still engaged with the hook, whereby they have been drawn into the recess 2; and clamped with a yielding force between the spring-plate 0 and the under side of the hook s. The latter contin ues to rotate and completes the twist, which secures the band to the gavel. The band-carrying arm then begins to move forward again behind the bound gavel, forcing the ends of the band from the hook and ejecting thegavel from the machine. As the gavel passes out from under the spring-compres or the latter springs back quickly to a vertical position, forcing the unbound grain back on the bindin g-table and effectually separating the straws of the old gavel from those assembling to formt o a new one. In this operation it is assisted by the wire extending from the holding-clamp to the risingneedle, which raises the loose straws above the line described by the point of the separator and supports them for the moment upon an incline, down which they are easily swept by the backward-springing rod. The grain thus assembling piles up against the rear side of the vertical separator. The band-carrying arm continues to rise, passes quickly back over it, descends, separates the grain to form another gavel, condenses it forward against the separator, which now acts again as acompressor, and the operation of the parts is repeated as before.

The wire is supplied from a spool or reel of herein shown, as well as the grain-reel, form the subjects of other contemporaneous applications for Letters Patent filed by me, and need not be herein described. I do not limit myself to the precise form or construction of the parts herein shown and described, but consider any mere modifications thereof which do not alter the principle and mode of operation of the machine or its respective parts or combinations as coming within the scope of my invention.

By the term continuously-rotating wheel 0, I do not mean necessarily a wheel rotating at all times continuously, but rather a wheel rotating continuously while the band-holder and twisting-head are in action, it being immaterial whether the movement of the wheel 0 be continuous or ,intermittent at other periods, but it is a material element to this part of the mechanism that the wheel rotate continuously from the time of commencing to loop or twist the wire till the twisting is completed and the gavel moved out of the way.-

I claim as my invention- 1.
